DevExpress是非常主流的.NET控件,目前全世界和中国都用很多用户使用,不过由于是英文版,初次接触的同学可能会觉得困难,这里就总结DevExpress常见的10个使用技巧。
1.TextEditor(barEditItem)取文本
string
editValue = barEditItem1.EditValue.ToString();
//错误,返回null
string editValue =
((DevExpress.XtraEditors.TextEdit)barEditItem).EditValue.ToString();
//精确,返回文本框内容
DevExpress使用技巧
2.ComboBoxEdit(barEditItem)添加Item
string
item =
"comboboxItem1";
((DevExpress.XtraEditors.Repository.RepositoryItemComboBox)this.barEditItem.Edit).Items.Add(item);
3.ComboBoxEdit(barEditItem)取文本
string
itemValue =
this.barEditItem.EditValue.ToString();
4.Ribbon控件
//添加Page
DevExpress.XtraBars.Ribbon.RibbonPage
ribbonPage = new
RibbonPage();
ribbonControl.Pages.Add(ribbonPage);
//添加Group
DevExpress.XtraBars.Ribbon.RibbonPageGroup
ribbonPageGroup = new
RibbonPageGroup();
ribbonPage.Groups.Add(ribbonPageGroup);
//添加Button
DevExpress.XtraBars.BarButtonItem
barButtonItem = new
BarButtonItem();
ribbonPageGroup.ItemLinks.Add(barButtonItem);
//添加barSubItem
DevExpress.XtraBars.BarSubItem
barSubItem = new
BarSubItem();
ribbonPageGroup.ItemLinks.Add(barSubItem);
//barSubItem下添加Button
barSubItem.AddItem(barButtonItem);
//奇异的删除Page问题(
DevExpress使用技巧)
while (this.ribbonControl.Pages.Count >
0)
{
ribbonControl.Pages.Remove(ribbonControl.Pages[0]);
//调试正常,运转报异常
}
while (this.ribbonControl.Pages.Count >
0)
{
ribbonControl.SelectedPage =
ribbonControl.Pages[0];
ribbonControl.Pages.Remove(ribbonControl.SelectedPage);
//运转正常
}
//遏止F10键Tips
(DevExpress使用技巧)
ribbonControl.Manager.UseF10KeyForMenu =
false;
//DX按钮
ApplicationIcon属性改动图标
右键 Add ApplicationMenu
添加evExpress.XtraBars.Ribbon.ApplicationMenu5.HitInfo
//在Tab页上点击右键的工作响应(DevExpress使用技巧)
void
xtraTabbedMdiManager_Event(object sender, MouseEventArgs e)
{
if (e.Button
== MouseButtons.Right && ActiveMdiChild !=
null)
{
DevExpress.XtraTab.ViewInfo.BaseTabHitInfo hInfo =
xtraTabbedMdiManager.CalcHitInfo(e.Location);
//右键点击位置:在Page上且不在封闭按钮内
if
(hInfo.IsValid && hInfo.Page != null &&
!hInfo.InPageCloseButton)
{
this.popupMenu.ShowPopup(Control.MousePosition);//在鼠标位置弹出,而不是e.Location
}
}
}
//在ribbon上点击右键的工作响应
private
void ribbonControl1_ShowCustomizationMenu(object sender,
RibbonCustomizationMenuEventArgs
e)
{
//禁掉原系统右键菜单
e.ShowCustomizationMenu =
false;
//右键位置:在barButtonItem上
if (e.HitInfo != null
&&
e.HitInfo.InItem
&& e.HitInfo.Item.Item is
BarButtonItem)
{
this.popupMenu.ShowPopup(Control.MousePosition);
}
//右键位置:在barSubItem中的barButtonItem上
else
if (e.Link != null
&& e.Link.Item != null
&&
e.Link.Item is
BarButtonItem)
{
this.popupMenu.ShowPopup(Control.MousePosition);
}
}
6.皮肤
//添加皮肤轨范集后注册皮肤(
DevExpress使用技巧)
DevExpress.UserSkins.OfficeSkins.Register();
DevExpress.UserSkins.BonusSkins.Register();
//设置皮肤
DevExpress.LookAndFeel.UserLookAndFeel.Default.SetSkinStyle("Liquid
Sky");
//若皮肤称号错误则按系统默许设置(第一个皮肤)
//GalleryFilterMenuPopup工作设置弹出选择菜单的“All
Groups”为中文
private void rgbiSkins_GalleryFilterMenuPopup(object sender,
GalleryFilterMenuEventArgs e)
{
e.FilterMenu.ItemLinks[n].Caption =
"一切皮肤";
//n=分组数+1
}
//GalleryInitDropDownGallery工作设置弹出皮肤列表的表头“ALL
Groups”为中文
private void rgbiSkins_GalleryInitDropDownGallery(object sender,
InplaceGalleryEventArgs e)
{
e.PopupGallery.FilterCaption =
"一切皮肤";
}
7.dockManager
将视图的状况信息保管到xml文件
dockManager1.SaveLayoutToXml("..\\UserConfig\\ViewInfo.xml");
导出xml中保管的状况信息
dockManager1.RestoreLayoutFromXml("..\\UserConfig\\ViewInfo.xml");
8.barManager
设置bar的字体与系统字体
barAndDockingController1.AppearancesBar.ItemsFont
= new Font(this.Font.FontFamily,
currentFontSize);
9.设置系统字体
DevExpress.Utils.AppearanceObject.DefaultFont
= new Font(this.Font.FontFamily,
currentFontSize);
10.treeView
为tree节点加右键菜单并选中该节点
private
void treeList1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button
== MouseButtons.Right)
{
DevExpress.XtraTreeList.TreeListHitInfo hi =
treeList1.CalcHitInfo(e.Location);
if (hi.Node != null &&
hi.Node.ImageIndex == 5) //叶子节点的ImageIndex == 5
{
TreeListNode node =
treeList1.FindNodeByID(hi.Node.Id);
treeList1.FocusedNode =
node;
this.popupMenu1.ShowPopup(MousePosition);
}
}
}
